Suard, W. Gurtner, L. Estey RINEX-type Broadcast Data Files for GEO Satellites ************************************************** In order to be able to easily exchange the binary data broadcast by Space-Based Augmentation Systems (SBAS) like EGNOS, WAAS, MSAS a group of individuals active in the SBAS community proposes a receiver-independent exchange format similar to the RINEX format widely used for the exchange of geodetic GPS and GLONASS tracking data. The group included Werner Gurtner (AIUB) and Lou Estey (UNAVCO) into the format discussion to insure maximum compatibility in the format appearance, description, and documentation with the existing RINEX formats. The proposal has been put into the public ftp archive of the International GPS Service in the same directory where all RINEX-related documents can be found: ftp://igscb.jpl.nasa.gov/igscb/data/format/geo_sbas.txt Please send any comments to Norbert Suard, CNES E-Mail: Norbert.Suard at cnes.fr Werner Gurtner, AIUB E-Mail: werner.gurtner at aiub.unibe.ch Lou Estey, UNAVCO E-Mail: lou at unavco.org RINEX Navigation Message Files for GEO Satellites ************************************************* The same group also proposes some minor clarifications/modifications to the original RINEX Version 2.10 "Navigation Message File for GEO Satellites" definition. This RINEX file contains interpreted navigation data of SBAS geostationary satellites usually extracted from above mentioned binary data. The proposal can be found in ftp://igscb.jpl.nasa.gov/igscb/data/format/rnx_geo_nav.txt Depending on the comments received we will then insert these clarifications/modifications into the existing RINEX V 2.10 documentation.
